The lights in the Mercedes-Benz Superdome went out early in the third quarter of Super Bowl XLVII in New Orleans.

San Francisco 49ers quarterback Colin Kaepernick was sacked for a loss of 6 yards on the last play before the lights went out with 13:22 left in the quarter at around 8:37 p.m. The delay lasted for 34 minutes.

Half of the lights went out initially, while another half remained on.

After a few minutes, the public address announcer said the Superdome was experiencing an interruption of electrical service and encouraged fans to stay in their seats.

Some fans did the wave to pass the time. Players milled around on the sidelines, some took a seat on the bench, other on the field. A few of the Ravens threw footballs around.

Officials gathered on the field and appeared to be talking to stadium personnel.

The NFL issued a statement during the third quarter of the game that read: "Stadium authorities are investigating the cause of the power outage. We will have more information as it becomes available."

CBS reported during the delay that the problem was caused by a failure of an outside power feed into the stadium.

Eric Eagan, Superdome spokesman, issued a statement that read, "power has been restored. We sincerely apologize for the incident."

Entergy New Orleans sent out a tweet on Sunday, "Power issue at the Super Dome appears to be in the customer's side. Entergy is providing power to the Dome."

Philip Allison, a spokesman for Entergy New Orleans, which provides power to the stadium, said power had been flowing into the stadium before the lights failed.

"All of our distribution and transmission feeds going into the Superdome were operating as expected," Allison said.

Jennifer Sabatelle, vice president of communications for CBS Sports, also issued a statement on how the power outage effected the telecast.

“Immediately after the power failure in the Superdome, we lost numerous cameras and some audio powered by sources in the Superdome. We utilized CBS’s back-up power and at no time did we leave the air. During the interruption, CBS Sports’ Steve Tasker, Solomon Wilcots and our studio team reported on the situation as a breaking news story, providing updates and reports while full power was being restored to the dome including our sets and broadcast booth. All commercial commitments during the broadcast are being honored.”
